Because the question is statistical which mean you will get more then one answers
9 x 10,000 is B. 18 times larger than 5 x 1,000.
This can be found by simplying multiplying each pair of number (9 x 10,000 = 90,000) and ( 5 x 1,000 = 5,000) then dividing the smaller value (5,000) into the larger value (90,000). This will give you the answer of 18.
I hope this helps!

Answer:
<h3>73220±566.72</h3>
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as;
CI = xbar ± z*s/√n
xbar is the sample mean = $73,220
z is the z score at 99% CI = 2.576
s is the standard deviation = $4400
n is the sample size = 400
Substitute the given values into the formula;
CI = 73,220 ± 2.576*4400/√400
CI = 73,220 ± 2.576*4400/20
CI = 73,220± (2.576*220)
CI = 73220±566.72
Hence a 99% confidence interval for μ is 73220±566.72
